Caltrans Fact Booklet (CFB)
DRISI collects and analyzes report statistics related to the fiscal status, physical and geometric extent, performance, and designation of the State's roadway systems. We research and provide ways in which our customers can access, display, and use these statistics. The CFB was formerly the Executive Fact Booklet.
Caltrans Fact Booklet (CFB) Web Application
DRISI is working on creating a web application for the CFB that will be easily accessed on your smart phone or any other electronic devise. Our goal is to eventually have all available Fact Booklets available at a glance from wherever you may be. Currently, we have two booklets ready to view in this way. Click on the link below to bring up the first view of the application.
California Quick Facts
California Quick Facts consist of commonly requested information compiled from many different sources within the state, both Caltrans and other California Agencies. Compiled by the Data Analysis and Reporting Branch.
California State Quick Facts
California County Quick Facts
(by County and Year)
California Road System (CRS) Maps
The California Road System (CRS) Maps display the official functional classification of each road. The Federal Highway Administration [FHWA) identifies functional classification as a key item in transportation data. Streets and highways are grouped into classes according to the service they provide.The functional classification is used by the Federal government in determining funding allocations which help local and State agencies pay for the maintenance of roads throughout their jurisdictions.
Collision Data on California State Highways
The accuracy of the data is subject to reporting levels of the law enforcement agencies
supplying the collision reports. The California Department of Transportation (Caltrans)
estimates that it receives all processable collision reports for fatal accidents, injury accidents,
and property-damage-only accidents occurring on state highways. This data excludes suicide,
non-motor vehicle related accidents, beat 902 (private property-school bus collision without
children on board on roadways within incorporated city).
The original collision data in this report was obtained from both California Highway Patrol
Fatality Analysis Reporting System (FARS) and Statewide Integrated Traffic Records System
To the extent this information is compiled or retained by Caltrans's
Highway Safety Improvement Program, it is privileged and precluded from
disclosure in litigation pursuant to Title 23 United States Code, section 409.
Disclosure herein is made pursuant to this privilege and subject thereto.
Geospatial Information Systems (GIS)
The GIS Program is the focal point for all GIS activities in the Department. Some important links:
Highway Performance Monitoring System (HPMS) Data
The HPMS is a federally mandated planning study designed by the Federal Highway Administration (FHWA) and implemented as a continuing information system that encompasses data collection, data analysis, and analytical modeling. Authority for the study is vested in Section 307 of Title 23, United States Code.
Highway System Engineering Products Data is in the Office of Highway System Information and Performance.
Data on highways and highway systems, the Strategic Highway Network (STRAHNET), National Highway System (NHS), California Road System (CRS) maps and route descriptions and route numbering for state highways. Highway System Engineering is now part of the Office of Highway System Information and Performance.
